BlowerDoor Measurements of large buildings

For large buildings, the airtightness become increasingly important in recent years.
The air tightness of the building envelope is an important component to improve. The energy quality of buildings

Large buildings are defined in BS EN 13829 buildings with an inner volume of more than 4,000 m³. This includes office buildings, hotels, shopping centers, industrial buildings, warehouses, schools, retirement homes, swimming pools, distribution centers, factories and warehouses, etc.

In BlowerDoor Measurements of large buildings, the pressure in all parts of the building required. The differences of pressure in the building shall not exceed 10% of the pressure generated according to EN 13829 are.
To measure the airtightness in large buildings, the fans are combined by us and are built in the right places to ensure. Thus the pressure in the whole building These are then controlled at a central location for the performance of the measurement.

Our office performs measurement Blower Door Measurements in smaller buildings (up to 4,000 m³) and BlowerDoor Measurements in large buildings (from 4,000 m³) this gives a quality of the skin.

Through our partnership with Belgium and Germany, we can perform measurements of extreme large buildings, where of course the quality and energy is equally as important.
